Abstract
There is provided an image processing method for generating a color image by using a color palette table, comprising the steps of a restriction step of restricting colors capable of being registered in the palette table, on the basis of gamut data of an image output means for outputting the color image, a formation step of forming the color palette table on the basis of color restriction obtained in the restriction step, and a generation step of generating the color image by using the colors registered in the color palette table, whereby excellent color matching between the color on a monitor and a color on a printer can be obtained.
Claims13
An image processing method for generating a color image by using a color palette table, comprising the steps of:
- restricting colors capable of being registered in the palette table, on the basis of gamut data of an image output means for outputting the color image;
- forming the color palette table on the basis of color restriction obtained in said restriction step;
- and
- generating the color image by using the colors registered in the color palette table.
An image processing method-comprising:
- an input step of causing an image formation means to form a target image on the basis of target data, and inputting image data obtained by reading the target image with an image read means;
- a correction step of correcting th e target data belonging t o an immediate range of a predetermined hue such that its saturation is raised and its hue is rotated, so as to generate the corrected target data;
- and
- a color process parameter generation step of generating a color process parameter on the basis of the image data and the corrected target data.
An image processing apparatus for generating a color image by using a color palette table, comprising:
- restriction means for restricting colors capable of being registered in the palette table, on the basis of gamut data of image output means for outputting the color image;
- color palette table formation means for forming the color palette table on the basis of color restriction by said restriction means;
- and
- color image generation means for generating the color image by using the colors registered in the color palette table.
An image processing apparatus comprising:
- input means for causing image formation means to form a target image on the basis of target data, and inputting image data obtained by reading the target image with image read means;
